    ima: define a canonical binary_runtime_measurements list format · d68a6fe9
    Mimi Zohar authored
    The IMA binary_runtime_measurements list is currently in platform native
    To allow restoring a measurement list carried across kexec with a
    different endianness than the targeted kernel, this patch defines
    little-endian as the canonical format.  For big endian systems wanting
    to save/restore the measurement list from a system with a different
    endianness, a new boot command line parameter named "ima_canonical_fmt"
    is defined.
    Considerations: use of the "ima_canonical_fmt" boot command line option
    will break existing userspace applications on big endian systems
    expecting the binary_runtime_measurements list to be in platform native
